#2 - Seems to be slightly out of focus...hard to tell with a picture this size.

#3 - B&W conversion could use more contrast. Subject is dead center of the picture (static, boring). To make the image a little more interesting you have to improve the composition. Digital Photography Composition Tips. Try to get down to the level of the eyes when you shoot children.

#4 - It's a nice image, but the harsh sunlight is causing the right side of her face to be washed out. On sunny days between 10:00 and 3:00 it's better to have the subject go into the shade if possible. You get a softer light and no harsh hot spots on the hair or face.

#5 - Not sure what the point of this image is.

What kind of camera did you take these with. Do you know the shot specs?

# 5 was actually taken last Memorial day at the lake using a telephoto lens. I was sitting on a pier and noticed in the distance that they were setting up a local band. A few harely Riders showed up and I thought it would make an interesting image.
